Vacuum Insulated Pipe is a key component enabling Chart to deliver the optimum turnkey cryogenic solution for a huge variety of liquid gas applications, all the way from food and beverage packaging to providing high rates of hydrogen and oxygen at space launch pads.

Two types of vacuum jacketed piping (VJP) systems (also referred to as vacuum insulated) — rigid and flexible — are available for process plant installations where long runs of piping are required to transfer LN2 from a bulk storage vessel at …

What is a Vacuum Jacketed Piping System? Vacuum jacketed piping, also called VJ piping or vacuum-insulated piping, is used to transfer supercooled gasses in liquid form. Cryogens like liquid helium, liquid oxygen, and liquid nitrogen must be kept cold during the transfer process, or some of the liquid will become gaseous and leak out.

VJP consists of two stainless steel pipes, an inner carrier pipe for liquid transfer and an outer pipe that supports and maintains vacuum insulation. The inner pipe is wrapped with radiation shield material (MLI), incorporating hydrogen getters and molecular sieves to preserve long-lasting vacuum quality and super-insulation performance.

Vacuum Insulated Pipe (VIP) is the preferred method for transporting cryogenic liquids and is unmatched in safety, reliability, and cost-effectiveness. Whether for storage, transfer, or final use purposes, vacuum-insulated piping is your most efficient option.

Our Vacuum-Jacketed Piping, Hoses & Accessories line epitomizes precision and reliability in cryogenic applications. Engineered with cutting-edge technology, these components ensure superior insulation, minimizing heat transfer and ensuring optimal efficiency in the transportation and handling of liquefied gases.

Vacuum Jacketed Pipe is essentially two pipes in one— an inner carrier pipe in which the cryogenic liquid is transferred, and an outer pipe that supports and seals the vacuum insulation, forming the “Vacuum Jacket” around the inner pipe. The inner line is suspended inside the outer jacket by a series of non-conductive supports.

VJ Systems is focused on the development of vacuum jacketed (VJ) systems that include piping, valves and other components primarily used to insulate cryogenic fluids such as Liquefied Natural Gas (LNG) from surrounding ambient environment. These piping systems will be factory fabricated in long spool sections and can be shipped to the site ...

Acme Cryogenics designs, manufactures and installs stainless steel super insulated Vacuum Jacketed Piping (VJP) systems used for the transfer of liquid nitrogen, oxygen, argon, natural gas, carbon dioxide and helium. Each VJP system is custom designed to meet the requirements of the application while keeping the system economics within budget.

VJ Piping is the preferred piping solution for the safe, reliable, cost-effective transfer of cryogenic liquids such as liquefied nitrogen, oxygen, argon, helium, and hydrogen, from storage tanks to points-of-use within a processing plant.
